lol !

i'm going around the house and cleaning out my car looking for quarters. with in mind knowing every one i find is a share of SIRI . hopefully it'll get down to dimes , found lots of those. i'm gonna make two more large purchases before Christmas and make a wish. funny thing being new to the market , so far i've lost an average of 55% of all my stocks , that i purchased at the same time. ( wouldn't be this low if i didn't have SIRI stocks ) in august i decided to teach english in thailand for 2009. i needed something to keep me busy while i'm there so i purchased stocks for the first time. i figure it'll be fun to ride the roller coaster and eventually earn extra cash and plan for my financial future.

out of these four , i was the most passionate for SIRI , and did my research and let my optimistic inhibitions get the best of me. does that make me a loser. yes it does ! considering i bought it at $ 2.25 a share , " sooo----
ooooooooo i'm a loser baby , so why don't cha kill me "

The inst. numbers in the teens come from Sirius pre-merger. I do not think they have accurate combined numbers yet.

54% comes from 75% (or so) inst. ownership for XM combined with the 18% (or so) inst owership of Sirius. If you look at share counts and the conversions of those XM shares, the numbers end up somewhere around 54%.

I did the math on this on Yahoo a while back. I do not think it is accurate anymore, but is where I believe the 54% comes from.

FWIW, I do believe that all of the sources are basing the number on estimates following closing of the merger. Some of them did the conversion of XM shares to Sirius, others just have it based on the last 13F filing for Sirius -- which was a pre merger filing.

The problem is that there have been no 13F filings yet since the merger closed. Scratch that, the 13F filings that have been filed are based on holdings as of 6/30/08, which of course is before the merger closed -- so none of these sources are likely even close.

You will have your more accurate answer in about 3 weeks -- as current 13F filings are due for holdings as of 9/30/08.

IMHO, the estimate will be much more than 20%, but probably lower than 50% -- because so many institutions dumped after the price tanked. But this is pure speculation on my part.
